Problems solved by technology

[0005] In order to overcome the above-mentioned shortcoming of monoculture and solve the problems such as slow growth, high mortality rate and serious fouling biological adhesion in the cultivation process of Pinctada martensii, the present invention provides a method suitable for culturing Pinctada martensii. The method can significantly increase the growth rate of Pinctada martensii in polyculture, reduce the mortality rate, reduce fouling organisms, increase the economic benefits of Pinctada martensii culture, and promote the sustainable development of Pinctada martensii culture

Embodiment 1

[0014] The polyculture of embodiment 1 Pinctada martensii and the luxurious Chlamys farreri (2009)

[0015] The polyculture method of the present invention: take 50 individuals of Pinctada martensii and Chlamys grandis respectively, measure their initial shell height, shell length, and shell width with a vernier caliper, weigh the shellfish with an electronic balance, and then mix the two shellfish. Divided into 5 groups: Group 1, 40 scallops; Group 2, 30 scallops + 10 pearl oysters; Group 3, 20 scallops + 20 pearl oysters; Group 4, 10 scallops + 30 pearl oysters; Group 5, 40 pearl oysters. Each group of shellfish was placed in 5-layer long cages, with 40 individuals in each layer, for the cultivation of Pinctada martensii and Chlamys farreri.

[0016] Samples were taken at the third month of breeding, and the shell height, length and width of the two shellfish were measured with a vernier caliper, weighed with an electronic balance, and the attached biomass was calculated ...

Embodiment 2

[0028] The polyculture of embodiment 2 Pinctada martensii and the luxurious Chlamys farreri (2010)

[0029] The polyculture method of the present invention: take 50 individuals of Pinctada martensii and Chlamys grandis respectively, measure their initial shell height, shell length, and shell width with a vernier caliper, weigh the shellfish with an electronic balance, and then mix the two shellfish. Divided into 6 groups: Group 1, 40 scallops; Group 2, 33 scallops + 7 pearl oysters; Group 3, 30 scallops + 10 pearl oysters; Group 4, 10 scallops + 30 pearl oysters; Group 5, 7 scallops + 33 pearl oysters; 6 groups, 40 pearl oysters. Each group of shellfish was placed in 5-layer long cages, with 40 individuals in each layer, and the mixed culture of Pinctada martensii and Chlamys farreri was carried out.

[0030] Samples were taken at the 6th month of cultivation, the shell height, length and width of the shellfish were measured with a vernier caliper, weighed with an electroni...

Abstract

The invention discloses a method for cultivating pinctada martensi. In the method, the pinctada martensi and chlamys nobilis are cultivated in proportion in the cultivation process. By utilizing the method for cultivating the pinctada martensi disclosed by the invention, the growth rate and survival rate of the pinctada martensi can be obviously improved, biomass liveweight adhered to the pinctada martensi is lowered, the cultivation time of the pinctada martensi is shortened and the economic benefits of products can be enhanced; and the method is suitable for popularization and application in aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a cultivation method of Pinctada martensii. Background technique [0002] Martensii pearl oyster ( Pinctada martensii Dunker ), also known as Hepu pearl oyster, is mainly distributed in tropical and subtropical sea areas such as Hainan, Guangdong, Guangxi and the southern part of the Taiwan Strait. Pinctada martensii is a sessile life, attached to rock reefs or cages with silk. It has the characteristics of fast growth and short breeding cycle. It is one of the main shellfish for seawater pearl cultivation. Its output accounts for more than 95% of the seawater pearl production in my country, and it has important economic value. However, due to the continuous expansion of the culture scale, the single culture method, and the imbalance of the shallow sea ecological environment and other factors, the culture of Pinctada martensii frequently suffers from slow growth, small indi...
